Help with Shock and Vibration Testing Shakers specifications:

Specifications Specifications are given under bare table conditions.
   Peak Sinusoidal Force:       The maximum amplitude of the applied force attained by the shaker table or armature during a test.  In a sine wave test mode, the force and velocity of the table and test sample will varying sinusoidally over time. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Frequency Range:       The vibration frequency range that the shaker is capable of providing in an unloaded state. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Displacement:       Typically the displacement given is the continuous peak-to-peak displacement, although some manufacturers may only state displacement between stops. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Peak Acceleration:       The maximum acceleration during testing without a test load.  The actual maximum acceleration will vary depending on the value of the combined mass of moving element and the test load. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Peak Velocity:       The maximum velocity amplitude attained by the shaker table or armature during an unloaded test.  In a sine wave test mode, the force and velocity of the table and test sample will varying sinusoidally over time. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.

Features
   Technology:       
   Your choices are...         
   Mechanical       Mechanical shakers use a rotating shaft with eccentrically positioned or unbalanced weights to generate vibration.  The shaft is usually driven by an electric motor.  The level of vibration can be adjusted by changing the position or size of the weights.  Although mechanical shakers have largely been displaced by electrodynamic shakers, they are still useful and reliable tools in certain applications. 
   Electrodynamic       Electromagnetic vibration or force generator using a coil and armature (voice coil motor) similar to that found in a speaker. 
   Hydraulic       Electrohydraulic or servohydraulic vibration or force generator systems.  Hydraulic systems are useful when large force amplitudes are required such as in testing large aerospace or marine structures or when the magnetic fields of electrodynamic generators can not be tolerated. 
   Piezoelectric       Vibration or force generator using the application of electrical charge and voltage to a sensitive piezoelectric crystal or ceramic element to generate deformation and motion.  Many accelerometers use the reverse effect to measure vibration. 
   Pneumatic       A vibration or force generator using pressure air to drive a table.  They are known as "air hammer tables," pneumatic vibration systems or single pneumatic rod systems. 
   Other       Other technology not listed. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Integral Slip Table / Multi-Axis Capability?       An integral slip allows horizontal or both horizontal and vertical testing of samples.  The slip table is a large flat plate that rests on an oil film placed on a granite slab or other stable base.  The slip table is attached to the shaker to provide horizontal testing capability. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Active Suspension?       Active suspension system compensates for environmental or floating platform variations. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Test Modes & Applications
   Test Mode:       
   Your choices are...         
   Random Vibration       In a random vibration test mode, the force and velocity of the table and test sample will vary randomly over time. 
   Sine Wave Vibration       In a sine wave test mode, the force and velocity of the table and test sample will vary sinusoidally over time. 
   Shock / Pulse Mode       In a shock test mode, the test sample is exposed to high amplitude pulses of force. 
   Other Test Mode       Other test modes not listed. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Application:       
   Your choices are...         
   Accelerometer Calibration       Shaker tables can provide a vibration source for calibration of accelerometers or other vibration sensors. 
   Mechanical Impedance Measurements       Mechanical impedance is the ratio of force to velocity, where the velocity is a result of that force only.  The inverse of mechanical impedance is mobility. 
   Modal Excitation Source       An excitation source imparts vibrations into a system for modal analysis. The system is stimulated or vibrated by the excitation source and then external accelerometers measurement the resulting vibration signature.  Modal analysis is the process of breaking complex structural motion into individual vibration modes.  Usually a Fast Fournier Transform (FFT) computer program is used to shift data from the time domain to the frequency domain.  Once the data is in the frequency domain analysis, analysis can breaks complex vibration signature down to component frequencies and relate the modes to specific features in the systems.  A piano wire coupler may be used to transmit the vibration to the test sample. 
   PIND Testing       Particle Impact Noise Detection (PIND) testing equipment detects any loose foreign particles that may be present in a hermetic package. The package is placed on a shaker table where it is in intimate contact with an acoustic transducer that drives an ultrasonic amplifier. 
   Product Qualification / Testing       Qualification of production components such as the testing of electronic or mechanical components for aircraft, spacecraft, military or other mission critical applications.  
   Reliability / Durability Testing       Testing to determine long term durability or reliability under accelerated vibration tests.  
   R&D / Product Design Verification       Verification of a product design or concept through vibration simulation and testing. 
   Seismic Simulation       Simulation of the shock and vibration signatures that occur during an earthquake or other seismic event. 
   Semiconductors / Electronics Screening       The testing or screening for resistance to vibration of microelectronic or semiconductor components such as memory, microprocessors or other integrated circuit chips.  Also, testing or screening of printed circuit boards or other electronic sub-assemblies. 
   Structural Fatigue Testing       Mechanical testing to determine the resistance of a material or product to repetitive applications of stress. Materials will fail at a much lower stress level under repetitive loads compared to a single, static tensile test condition.   
   Transportation / Aerospace Simulation       Simulation of the shock and vibration signatures that occur during an automotive or other transportation of equipment or products. 
   Other       Other application not listed here. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
